Here are the key points of what we know about the Hyperloop system Musk wants to build:

The first full-size Hyperloop track (read: not this test track) would run from LA to SF.

Musk’s design group estimates the cost of the LA -> SF track to be around $6 billion.

That trip, based on totally conceptual estimates, would take 35 minutes.

The conceptual top speed is roughly 760 MPH.

Musk believes the Hyperloop would work above ground or below ground.

The concept works by sending pressurized pods through a tube. This tube is (theoretically/hopefully) kept at a partial vacuum, allowing the vehicle to move within significantly reduced air resistance. The pod itself floats on a cushion of air, with the pod’s design meant to utilize air-pressure buildup — which would generally slow a vehicle down — to its advantage.
